BTS light stick Ver 1 is the oldest and it looks simple because it is just like a flashlight🔦 so it only has basic white light and cannot connect to your phone or change colors, and it is bigger and heavier than the others so it feels a little hard to hold for a long time🪩.
Ver 2 is a little smaller and lighter than Ver 1 and it can use Bluetooth at concerts so the staff can control the lights, but you cannot use Bluetooth at home and it still only has white light, but it has more light modes like slow and fast flashing💡.
Ver 3 looks more modern and has the new BTS logo inside the globe so it can connect to your phone with Bluetooth and you can change the colors using the BTS light stick app, and it is easier to hold and comes with photo cards, so many fans like this version because it is bright and fun to use at home or at concerts📱.
SE, which means Special Edition, is called the “Map of the Soul” version and it looks a little different because it is more shiny and modern, and it does not have beads inside like the older ones so it is more quiet, but it can also connect to your phone with Bluetooth and you can change the colors just like Ver 3, and it is a little heavier but feels more special for collectors✨.
So, the main differences are the look, the size, the light features, and if you can connect to your phone or change colors, and the SE is the newest and most modern with the best features for fans who want something special and shiny to use at concerts or at home🎉.
